Histotechnology Facility


The Histotechnology Shared Resource provides services for fixing, processing and paraffin or OCT-embedding of all types of tissues for light microscopy (e.g. routine stains, immunohistochemistry or in situ hybridization). The Facility staff performs routine hematoxylin, eosin staining, immunochemistry and FISH staining, as well as specialized staining and slide preparation for immunohistochemistry and in situ hybridization. Frozen sectioning is also available, including consultation regarding freezing and fixing techniques to optimize experimental results.
